AClEl'AIxJZJ].S FURN ESS HATELY, OF CHICAGO, ILLINOIS, ASSIGNOR T0 ILLINOIS, A CORPORATION GUARD COMPANY, or CHICAGO,

To all whom t may concern Be it known that I, CHARLES FURNss HATELY, a citizen of the United States, re

siding at Chicago, in the county of Cook and State of Illinois, have invented certain new .and useful Improvements in VCattle-Guards,

of which the following is a specification.,

This invention relates t0 cattle guards, I

Y and has reference more particularly to cattle guards of the type that are made from sheet pending upon th metal and lare vformed with integral teeth struck or stamped up from the body portion j the guard. A cattle guard of Y Athe general class and structural type to which d thebars 12, the portions of the flanges 10 lying in the kerfs 11 the present inventionv belongs is illustrated dated October 12, 1915; and the object of the invention is to improve the utility and eiliciency of sheet metal guards of the-class n' vface of thel guard. To this end, acattle my present invention comprises guard of features and details ofstructhe various 'tureA hereinafter described andmore particu-v larly defined in the appended claims.

In orderv that my invention may be readily understood and appreciated by 'those vfamiliarfwith th'e'art in which belongs, n in the v.accompanying I Vhave illustrated drawings one practical and workable embodiment thereof; and referring theretol` Figure `1 is a top plan viewof a cattle guard of my invention shown as applied-in use, a' fewonlyof the tooth bars being shown A in full detail since they are all alike.

Figl 2-is ana-enlarged fragmentary-per-v spective view of one of the tooth bars. l Figs. 3 and 4L are sections on the corresponding lines of Fig. 1. n

Referring to the drawing, 45 designates the ties and 6 the rails of a railway track to which the cattle guard Vis principally applied in service. As herein shown the complete guard is made in a plurality of seictions disposed sideV by side, each section comprising a series of four parallel tooth bars rigidly connected in spaced relation. a description of one will suffice for all.

Speccation of Letters Patent.

Y downwardly to kspacing members teeth lying substantially in latter, feature, however,

My present improve-- Y ments have to do with the structural form of consist of thefean 16 of the NATIONAL SURFACE OF ILLINOIS.

CATTLE-GUARD.

A designates as an entirety each of the tooth bars, the ends 7 of .which are-flat and are riveted to transverse angle bars 8, these latter resting upon the ties 5 and being secured to the latter as by spikes 9.y The marginal portions of, each bar are bent 1 form underlying ribs or flanges 1Q, and these latter lit intotransverse kerfs 11 formed in underlying angle bars 12, of which one -or mo-re may be used de-l length of the guard, the angle :bars 12 serving as connecting and and also preferably resting upon-the ties 5. To lock the tooth bars A to are swaged laterally as indicated at l0v 'in Fig. iso as to lform a bar that lies between the flangeslO there are struck upY two rows of substantially vertical main teeth 13 of inverted 'V-shape, these they vertical planes of the ribs or flanges 10.

The guard as ,thus` fardescribed is substantiallythe guard disclosed in the Letters Patent hereinabove referred to, with the eX- cep'tion that the intermediate skeleton web portion is of arch form instead of iiat, this forming no part of the present invention.

the tooth lbar itself, and, tures next to be describecl v Out of each of the main teeth'13 is struck an auxiliary toothl14 that extends laterally of the main tooth on `theouter side of the latter and. preferably having an upward and outward inclination of approximately 45. There' is also preferably employed an additional row of teeth -15 lying parallel` with Y Patented Apr. 8,1919.' Application filed October 25, 1917. Serial No. 198,434. Y' i' lock. From the intermediate portion of the and substantially midway -between the two rows of mainteeth 13. Thesepintermediate teeth 15 are very simply andV easily prof du-ced by simply severing alternate limbs zigzag skeleton structure that is created by the punching out of the Vmain teeth 13, these limbs being severed transversely and the longer portions lof the severed limbsrbeing bent upwardly as indicated in Fig. 2, thereby forming the upwardly pointing teeth 15, while the shorter portions form substantially horizontal prongs or teeth 17.

One result of the rforegoing structure is that the number of teeth in a given surface iio area of the guard is doubled as compared with the structure of the Bolinger patent a'bove referred to, andconsequent y the spacventing smaller hoofed animals such as hogs l and sheep from crossing or trespassing on Manifestly, the auxiliary teeth 14: serve to reduce the width of the open spaces between the bars, while the auxiliary teeth 15 similarly serve to reduce the spacey between the marginal teeth 13 of each bar. The result is a guard, the surface area of which is so thickly studded with projecting points 'that it is impossible for any farm animals to walk upon or over it.

While I have shown and described a simple and practical embodiment of the invention readily lending itself to economical manufacture by mere punching and swaging operations, it will' be understoodthat the principleJ of the invention is capable of embodiment in tooth bars otherwise made and ydiffering somewhat lin specific detail. Hence, I` do not limit the invention to the particular structure herein shown except to the extent indicated in specific claims.

I claim:

1'. A. cattle guard comprising a plurality of spaced,bars,'each -providedwith a longitudinal row of'upstanding main teeth, and said-main teeth carrying upwardly inclined auxiliary teeth struck out from the sides of saidmain teeth and merging their b'ases with the latter. i

2.- A cattle guard comprising a plurality of spaced bars, each provided on a longitudinalmargin thereof with arow of substantially vertical mainl teeth, and said main teeth carrying flat auxiliary teeth struck out from th sides of said main teeth and merging at their bases with the latter and lying in a planeformingl an acute angle with the portionsl of said main teeth above the bases of saidk auxiliary teeth.

3; A cattle guard comprising a plurality of spaced bars,"eachprovided on alongitu- This renders the guard much moreV dinal margin thereof with a row of substantially vertical inverted Vf-,shd-Ped main teeth, and saidmain teeth having punched therefrom upwardly and outwardly inclined inverted V-Shaped auxiliary teeth struck out from the sides of said main teeth and merging at their bases with the latter and lying in a plane inclined at an angle of approximately forty-tive. degrees to the portions of said main teeth above the bases of said auxiliary teeth.

et. A cattley guard comprising a plurality of separated spaced `ba-r,s,'each for-med with parallel vertical flanges and a, connecting web, each of said vertical Vflanges having on its upper edge a row of verticalteeth struck upwardly from said web, and said webcarryingr an additional row of verticall teeth struck upwardly therefrom, andalso a series of substantially horizontalk prongs created by the striking up of saidl rows of teeth.

5. A cattle 'guard comprising a plurality of separated spaced bars, each formed -with parallell vertical marginal flanges and an arched connectingweb, ea h of said vertical flanges having on its upper edge a row of teeth struck upwardly from said web and lying in the vertical plane of the flange, and said web carrying an additional row of shorterl teeth struck upwardly therefrom substantially midway between said marginal rows, and also a series of vsubstantially horizentralV prongs created by the strikingup of Vsaid rowsof, teeth. '6. A; cattle guardy comprising a plurali-ty of spacedfbaraeach provided on the longitudinal margins thereof with rows of upstandingV teeth carrying outwardly and'upwa-rdly projecting auxiliary teeth, and with an additional longitudinalv row of:v teeth between marglnalrows, 7. A cattle guard comprising a plurality of spaced'bars, each provided on the longitudinal margins thereof with rows of upstanding teeth carrying outwardly and upwardly projecting auxiliary teeth, and fur-ther provided with an intermediate row of shorter teeth struck up from the intermediate portion of the bar.'
